1. Vignole Rails / Flat Bottomed Rails

Vignole rails, also known as flat-bottomed rails, are the most common Rail shapes/type of railway rail used around the world. They are symmetrical vertically and have a flat base that allows them to sit on pads/sleepers. These rails are typically made from steel and come in a range of different shapes and sizes, depending on their intended use.

The most common types of vignole rails include the BS 113A railway rail and the UIC60 railway rail. The BS 113A railway rail is used in the UK and other countries, while the UIC60 railway rail is used in Europe and other parts of the world. Both of these rails are designed to withstand heavy loads and have a long service life.

2. Crane Rails

Crane rails are rails designed specifically for use in industrial crane tracks. They are typically made from high-strength materials such as alloy steels, and are designed to provide high load-bearing capacity and durability. Crane rails are also designed to resist wear and deformation, which can occur due to repeated use by heavy industrial equipment.

Crane rails come in a variety of sizes and profiles, depending on the specific application. They are typically bolted directly to the rail ties or sleepers and are often coated with a special paint or coating to help protect them from the elements and prevent rust and corrosion.

Crane rails are flat-bottomed rails used to support very large axle loads from crane vehicles. These rails are typically much thicker and heavier than standard railway rails, with a much thicker web that provides added strength and support.

Crane rails are not usually grouped with railway rails because they are used in different applications. They are typically continuously supported, meaning that they do not sit on discrete pads/sleepers/ties. Instead, they are mounted directly onto the ground or other structures.

Some of the most common types of crane rails include the A65, A75, A100, A120, A150 profiles, as well as MRS87, crane rail 87, crane rail 89, and crane rail 125 profiles.

3. Check Rails

Check rails are a special Rail shapes/type of rail used to guide trains around sharp curves or to direct them along a specific route. Unlike normal flat-bottomed rails, check rails are not designed to be run on top of them. Instead, they run against the wheels of the train to provide additional steering forces.

Various rails can be used as check rails, including normal flat-bottomed rails in some circumstances. However, the most common check rail sections used today are the 33C1, U69, and UIC33, depending on the specification being used.

Check rails are typically used in areas where extra steering forces for the axles may be needed, such as very sharp curves or at switch and crossings. They essentially restrain the flat back of the wheel to direct it around sharp curves or to the correct route set at switches and crossings.

4. Grooved Rails

Grooved rails, also known as tramway rails, are used to provide flangeway clearance for railway vehicles such as trams. These rails have a deep and wide groove that allows the tram wheels to pass without fouling the road surface.

Grooved rails are typically made from steel and have a head, web, and foot like flat-bottomed rails. However, because of the groove, they also have an extra part called the keeper, which keeps the road away from the wheels.

Grooved rails are typically laid into road or grass-type areas, and only the head, groove, and top of the keeper are visible. The keeper sometimes serves a double function, not only restraining the road from obstructing the rail wheels but also providing a built-in check rail. However, some experts have expressed concern about using the keeper as a check rail, as its thickness is generally quite small, and the wear allowance is also small.

10. Flat-footed rails

Flat-footed rails, also known as bullhead rails, were once a common Rail shapes or type of railway rail. However, they are no longer used for new construction and are mainly found on heritage railways and museum exhibits. These rails have a distinctive ‘bulge’ on the top of the railhead, giving them their bullhead name. They were used extensively in the UK until the 1960s and are still used in some countries.

Flat-footed rails are so named because their base is flat and does not require any special pad or sleeper. This was because they were originally laid directly onto stone blocks, known as ‘stone blocks and chairs’. The stone blocks would support the weight of the rail and train, and the chairs would keep the rail in place. Flat-footed rails were typically made from wrought iron and were very heavy.

11. T-rails

T-rails are a Rail shapes/type of railway rail that is shaped like a T when viewed from the end. They are commonly used in heavy-duty applications, such as in crane rail tracks or in mining operations. T-rails are designed to provide high strength and durability, and they are often made from high-strength materials like alloy steels. T-rails are similar to girder rails in that they have a thicker web than standard railway rails, providing additional strength. They also have a flange on one side of the rail, which provides lateral support and helps to prevent the rail from bending or twisting under heavy loads. T-rails are typically bolted directly to the rail ties or sleepers, rather than being mounted on top of them.

12. Guard rails

Guard rails, also known as guide rails, are used to prevent trains from derailing or leaving the track. They are typically made from heavy steel or concrete and are installed at strategic locations along the track, such as at curves, bridges, and steep inclines. Guard rails are designed to absorb the energy of a train that has derailed, helping to prevent damage to the train and surrounding infrastructure. Guard rails are typically installed parallel to the track and are bolted directly to the rail ties or sleepers. They are often coated with a special paint or coating to help protect them from the elements and prevent rust and corrosion.

13. Ribbon rails

Ribbon rails are kind of Rail shapes/type of rail that is designed to be very lightweight and portable. They are typically used in temporary or emergency situations, such as in disaster relief efforts or military operations. Ribbon rails are made from lightweight materials like aluminum or plastic, and are designed to be quickly and easily assembled and disassembled. Ribbon rails are typically laid directly on the ground or other flat surface, and are not typically bolted or anchored in place. Instead, they rely on their own weight and the weight of passing trains to keep them in place.

14. Monorail tracks

Monorail tracks are a type of rail system that uses a single rail to support and guide the train. They are commonly used in theme parks and other amusement attractions, as well as in some industrial applications. Monorail tracks are typically made from steel or other high-strength materials and are designed to provide high load-bearing capacity and durability. Monorail tracks can be either elevated or ground-level, depending on the specific application. They are often bolted directly to concrete supports or other structural elements and are typically coated with a special paint or coating to help protect them from the elements and prevent rust and corrosion.
